What are the terms of the Rubik s Cube, and what are the professional terms of the Rubik s Cube

Fourth-order Rubik's Cube basic knowledge tutorial, explanation of basic terms.

1. Order: The number of blocks arranged on each side of the Rubik's cube. The 3*3*3 Rubik's cube that we usually see is called the third-order Rubik's cube.

2. Restoration: The process of restoring the Rubik's Cube from a chaotic state to a six-sided color.

3. Formula: For a certain state of the Rubik's Cube, the steps used to rotate the Rubik's Cube to achieve another target state. It is important to emphasize that memorizing formulas does not use the brain, but muscle memory.

4. POP (Pop Up Flying Edge): When turning the Rubik's Cube, there are moving blocks falling out, and the Rubik's Cube is scattered. In the current competition, players need to install the Rubik's Cube back before they can continue the game.

5. DNF (Did Not Finish Forfeit): The Rubik's Cube Restorer feels that he cannot restore the Rubik's Cube within a satisfactory time and gives up the game.

6. Sub XX (subtraction less than XX seconds): The average restoration speed of the Rubik's Cube is less than XX seconds. For example, sub30 means that the average restore time is less than 30 seconds.

The first letters of up (up), down (down), front (front), back (back), left (left) and right (right) in English represent the six sides of the Rubik's cube respectively, namely you (up), d (down), f (front), b (back), l (left), and r (right). When rotating the right layer of the Rubik's cube, if you rotate 90° clockwise from the right side, you will use r to indicate the rotation, and if you turn 90° counterclockwise, you will use r'This rotation is described, and if it is rotated 180° clockwise, it is represented by R2. In addition, the movement of the interlayer rl'It is simply written as rs (indicating that the left and right layers are rotated 90° clockwise with the right layer as the reference at the same time), and the movement of the interlayer rl is simply written as ra (i.e., the right layer rotates 90° clockwise, and the left layer rotates 90° in the opposite direction to it), and (rsfs)3 means that the RSFS action is repeated 3 times.

Order: The order refers to the number of blocks on each side of the Rubik's cube, for example, there are 3 small blocks on each side of the third-order Rubik's cube.

Restoration: refers to the process of going from a non-original state to an original state of the Rubik's Cube.

POP (Flying Edge): Refers to the situation in which some part of the Rubik's Cube is detached from the Rubik's Cube during the restoration, and if it appears in a match, it is considered an invalid recovery process.

DNF (Waiver): Did Not Finish means that the Rubik's Cube restorer feels that he cannot complete the Rubik's Cube within his or her satisfactory time and abstains, and can have a DNF in the match.

Here's how to play the Rubik's Cube:

Material preparation: Rubik's Cube.

1. Face the top of a Rubik's Cube to the first cross of the same color.

2. Align the T-shaped surface from the first side to the fourth side.

3. Match the four edged color blocks of the second layer of the Rubik's Cube and the first two layers.

4. Spell a cross with the same color on the top surface of the Rubik's Cube.

5. Adjust the orientation of the top-level role block, and match the yellow side of the page.

6. Adjust the order of the same color block on the top layer of the Rubik's Cube.

7. Adjust the order of the top layer of the same color block, and finally restore the Rubik's Cube to the same color on each side.

The Rubik's Cube, also known as the Rubik Cube, was first invented in 1974 by Professor Ernor Rubick of the Budapest School of Architecture in Hungary. The Rubik's Cube has a variety of gameplay methods such as racing, blind twisting, and single twisting, and it is one of the most popular intellectual games.

In the usual sense, the Rubik's Cube refers to the third-order Rubik's Cube in the narrow sense. The third-order Rubik's Cube shape is usually a cube and is made of elastic hard plastic. The regular racing game is to disrupt the Rubik's Cube and then restore it in the shortest time.

In a broad sense, the Rubik's Cube refers to all kinds of geometry that can be disrupted and restored by turning.
